High water leads to road closures in the United Counties of SDG.

CORNWALL, Ontario - The Raisin Region Conservation Authority is maintaing a flood watch for the Cornwall area, with water levels expected to increase over the coming days.

The agency, which monitors the flood-plain surrounding Cornwall, said there's no indication yet that flood waters will increase to the point where property damage will become a factor.

"Most of the excess water is contained within the flood plain," the agency said in a media release. "The flood-plain is land where water is known to collect during spring thaw and therefore development is restricted anyways. It is not uncommon to see fields full of standing water, which will eventually recede when the river flows settle down."

There are some low-lying roads and private laneways within these flood-prone areas which have been overtopped.

Chapel Road where it crosses the Beaudette River near Apple Hill, a portion of McGillivray Road between Williamstown and Martintown along the Raisin River and County Road 30 from Kenyon Concession Road 5 to Kenyon Concession Road 4 are closed due to flooding.

Flows in the Raisin River have risen 0.7 meters in the past 48 hours, and 1.5 meters in total over the past week. 

The current flow rate of the Raisin River is 82 cubic meters per second. This is not uncommon; the spring freshets of 2008, 2001 and 1998 had similar flow rates.

Last year’s flow by comparison peaked at only 52 cubic meters per second.

There are several ice jams along the length of various rivers and creeks which may back up the water somewhat. Flows are expected to rise over the next few days due to melting snow pack still in the upper reaches. This could cause additional flooding.
